Historical Standard: ASTM C270-05 Standard Specification for Mortar for Unit Masonry
SUPERSEDED (see Active link, below)
1.1 This specification covers mortars for use in the construction of non-reinforced and reinforced unit masonry structures. Four types of mortar are covered in each of two alternative specifications: ( 1 ) proportion specifications and ( 2 ) property specifications.Note 1
When the property specification is used to qualify masonry mortars, the testing laboratory performing the test methods should be accredited in accordance with Practice C 1093.
1.2 The proportion or property specifications shall govern as specified.
1.3 When neither proportion or property specifications are specified, the proportion specifications shall govern, unless data are presented to and accepted by the specifier to show that mortar meets the requirements of the property specifications.
1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.5 The terms used in this standard are identified in Terminologies C 1180 and C 1232.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
